The genuine creator creates something that has a life of its own, something that can exist and function without him. This is true not only of the writer, artist and scientist, but of creators in other fields...With the noncreative it is the other way around: in whatever they do, they arrange things so that they themselves become indispensable.

We shall assume that what each man does is based not on direct and certain knowledge, but by pictures made by himself or given to him. If his atlas tells him the world is flat he will not sail near what he believes to be the edge of our planet for fear of falling off. If his maps include a fountain of eternal youth, a Ponce de Leon will go off in quest of it. If someone digs up yellow dirt that looks like gold, he will for a time act exactly as if he has found gold. The way in which the world is imagined determines at any particular moment what men will do. It does not determine what they will achieve. It determines their effort, their feelings, their hopes, not their accomplishments and results.

Because we do not understand the brain very well we are constantly tempted to use the latest technology as a model for trying to understand it. In my childhood we were always assured that the brain was a telephone switchboard. ('What else could it be?') I was amused to see that Sherrington, the great British neuroscientist, thought that the brain worked like a telegraph system. Freud often compared the brain to hydraulic and electro-magnetic systems. Leibniz compared it to a mill, and I am told some of the ancient Greeks thought the brain functions like a catapult. At present, obviously, the metaphor is the digital computer.

Consciously or unconsciously, every one of us does render some service or other. If we cultivate the habit of doing this service deliberately, our desire for service will steadily grow stronger, and will make, not only our own happiness, but that of the world at large.
